Kirsty Wark reunites peace campaigners who travelled to Baghdad in 2003 to act as human shields, placing themselves at strategic sites to deter bomb attacks from the US and its allies. Joining Kirsty to discuss this incredible journey are Joe Letts, who owned two of the buses used to transport the protest, former diplomat Sue Darling, Parisian truck driver Alex Benuraud, and journalist Charlotte Edwardes.
